Filter Rock
Also known as: filter stone, filter aggregate, transition rock, filtration rock
Graded rock for filtration layers in drainage and stormwater systems.
Filter rock is a specifically graded aggregate used to create filtration layers that allow water to pass while preventing soil migration. Used between different soil or aggregate layers in drainage systems, stormwater ponds, and dam construction. The gradation is engineered to match the adjacent materials — the filter criteria prevent piping and clogging.
